I’m currently using a 5 star scale because I was having difficulty maintaining my list using a 10 point scale. A 5 star scale is less susceptible to changes and/by overthinking because it covers a broader range per point. It also has a middle score (3) and thanks to the less points overall it condenses the mediocre scores on a 10 point scale, 5 and 6, into one score.
